Chinese Whispers Test: Can a value survive a 5-agent pipeline intact?
|
|
|
|
Tests the core value proposition: Tardygrada guarantees that once a value
|
|
is committed by agent 1, no other agent in the chain can modify it.
|
|
The system detects tampering, enforces integrity, and proves the chain.
|
|
|
|
Three scenarios:
|
|
1. HONEST chain: same message passed through all 5 agents -> all verify
|
|
2. TAMPERED chain: agent 3 tries to change the message -> caught
|
|
3. CONSISTENCY chain: agent 4 submits a value that contradicts agent 1 -> caught
